Water temperature
Temperature observations measured on ferries during the last week between Helsinki-Travemunde. Map is showing the current position of the ship making the measurements and the latest observations. The color of the route indicates the temperature on the shipping route.
Salinity
Salinity observations measured on ferries during the last week between Helsinki-Travemunde. Map is showing the current position of the ship making the measurements and the latest observations. The color of the route indicates the salinity on the shipping route.
Algae observations
Chlorophyll observations (algae) measured on ferries during the last week between Helsinki-Travemunde. Map is showing the current position of the ship making the measurements and the latest observations. The color of the route indicates chlorophyll concentration on the shipping route.
Amount of blue-green algae
Amount of blue-green algae (phycocyanin concentration) measured on ferries during the last week between Helsinki-Travemunde. Map is showing the current position of the ship making the measurements and the latest observations. The color of the route indicates amount of blue-green algae on the shipping route.
Turbidity
Turbidityobservations measured on ferries during the last week between Helsinki-Travemunde. Map is showing the current position of the ship making the measurements and the latest observations. The color of the route indicates turbidity on the shipping route.
The data has been produced in cooperation with JERICO-RI, the research infrastructure for European coastal waters (Joint European Research Infrastructure network for Coastal Observatory).
